This research produced active films based on chitosan films, which were filled with Vietnamese coriander extract from 95% ethanol. The parameter such as amount of the Vietnamese Coriander extract filled in chitosan film was studied. It was found that the chitosan film turned to be opaque with yellow-green color when filled with the extract. In addition, the film was then thicker but had the lower moisture content. From the FTIR measurement, it was observed that the extract did not interact with the chitosan. For the antioxidant test result, it showed that the extract enhanced the antioxidant ability
